Chaotic motion in multi-black hole spacetimes and holographic screens
William Hanan, Eugen Radu
We investigate the geodesic motion in dimensional Majumdar-Papapetrou multi-black hole spacetimes and find that the qualitative features of the D=4 case are shared by the highe…
Einstein-Yang-Mills solutions in higher dimensional de Sitter spacetime
Yves Brihaye, Eugen Radu, D. H. Tchrakian
We consider particle-like and black holes solutions of the Einstein-Yang-Mills system with positive cosmological constant in d>4 spacetime dimensions. These configurations are sphe…
Cosmological monopoles and non-abelian black holes
Yves Brihaye, Betti Hartmann, Eugen Radu +1
We discuss magnetic monopole solutions of the Einstein-Yang-Mills-Higgs equations with a positive cosmological constant. These configurations approach asymptotically the de Sitter…
Euclidean solutions in Einstein-Yang-Mills-dilaton theory
Y. Brihaye, E. Radu
We present arguments for the existence of a new type of solutions of the Euclidean Einstein-Yang-Mills-dilaton theory in dimensions. Possesing nonvanishing nonabelian charges…
Features of gravity-Yang-Mills hierarchies in d-dimensions
Eugen Radu, Cristian Stelea, D. H. Tchrakian
Higher dimensional, direct analogues of the usual d=4 Einstein--Yang-Mills (EYM) systems are studied. These consist of the gravitational and Yang-Mills hierarchies in d=4p dimensio…
